In 1963, the American Institute of Electrical Engineers (AIEE) and the Institute of Radio Engineers (IRE) were merged into the Institute of Electrical and Electronics Engineers (IEEE). The IEEE logo or badge is a merger of the badges of those two organizations. The AIEE badge had the kite shape which was meant to symbolize Franklin's famous kite. The IRE badge had the two arrows that symbolize the right hand rule of electromagnetism. No letters clutter the badge because a badge without letters can be read in any language.
